The combination Wi th a metallic railwaytie, having a centrallongitudinal strengthening-rib on its under side, formed withrectangularl bolt-holes near each end, and dowlr wardly-depending sidesor flanges, formed with reinforced seats or recesses registering witheach other, of the bolts, comprising the elongated heads, the squareshoulders and the screw-threaded shanks, substantially as described.

LI. The combination with a metallic railwaytie, having a centrallongitudinal strengthening-rib on its under side, formed Withrectangular boltholes near each end, and downwardly-depending sides orflanges, formed with opposite alined reinforced seats or recesses, ofthe bolts having elongated heads, and shoulders and theinclinedscrew-tjhread ed Shanks, the clips having beveled upper sides and thenuts, substantially as described.

In testimony whereof I aiiix my signature in presence of two Witnesses.
